Dimensions

According to Pica's article card for 581-12 the chalk measures 12 mm and is 85 mm long - that is, a 12 x 12 mm square cross-section. On the current range page the manufacturer gives a 13 mm tip and 90 mm length. Shape and colour are the same in both sources: a square, white chalk.

Which surfaces it marks

Besides blackboards, Pica lists the chalk as suitable for brick, stone, concrete, plastic, paper, wood and rubber. In its product sheet the manufacturer rates materials with up to three stars: the chalk is ideal (3 stars) for stone and concrete, plastic and leather, and suitable (2 stars) for processed wood, metal, dry raw wood and dry rubber.

Square shape

The square cross-section sets the 581 apart from Pica's forester chalks, which are hexagonal. The manufacturer highlights the square shape and rich colour as the article's main characteristics.

Packaging

The manufacturer supplies the chalk in a box of 12; the current range page lists the pack as "Blackboard chalk 12 pack".
